摘要: 为研究滤嘴通风对加热卷烟气溶胶释放的影响,制备了滤嘴空腔段通风孔数量分别为0、2、4、6、8的1#—5#加热卷烟样品,分别采用微探针取样原位气溶胶表征方法和热电偶测温法考查了通风孔数量对气溶胶物理特性和温度的影响规律。结果表明:滤嘴通风改变了气溶胶的粒径分布,通风孔后气溶胶的粒数浓度和体积浓度随通风孔数量的增加呈降低趋势,5#样品气溶胶体积浓度相较于1#样品降低了57.4%,通风减小了气溶胶的粒数中值粒径,但其随通风孔数量的变化规律不显著;通风孔后气溶胶的温度随通风孔数量的增加呈降低趋势,5#样品气溶胶温度相较于1#样品降低了23.0℃;通风孔前、后气溶胶体积浓度与温度均呈现中轴线处高,且沿径向随距离增大逐渐降低的分布趋势。Abstract: In order to study the influence of filter ventilation of heated tobacco products on aerosol released, 1#—5# heated tobacco products samples with 0, 2, 4, 6, and 8 ventilation holes set at cavity section of filter were prepared. With an in-situ aerosol characterization method with microprobe sampling and a thermocouple temperature measurement method, the effects of ventilation on the physical properties and temperature of aerosol were investigated and analyzed. The results showed that filter ventilation changed the particle size distribution of aerosol in heated tobacco products. The particle number concentration and volume concentration of aerosol behind ventilation holes in heated tobacco products decreased with the increase of the number of ventilation holes. The reduction rate of particle volume concentration of aerosol from sample 5# was 57.4% compared with sample 1#. Ventilation reduced the count median diameter of aerosol. However, the change of count median diameter with the number of ventilation holes was not significant. The temperature of aerosol in front of and behind ventilation holes decreased with the increase of the number of ventilation holes. The aerosol temperature of sample 5# was 23.0 ℃ lower than that of sample 1#. The particle volume concentration and temperature of aerosol in front of and behind ventilation holes were higher at the central axis and lower along the radial distance.
